Custom Web Service Responses

TimAdams75

Hi,

I have been designing a web service based integration for one my customers where NAV will broker a relationship between their web site and 3PL, but I have hit a slight stumbling block.

The message that the website passes me has a lot of nodes and I would like to be selective with the nodes I return back i.e. Order No. and Status.

My question is, if I use a VAR XMLPort as a parameter of the codeunit all of the nodes are returned to the caller. If I set the XMLport to import only and remove the VAR element of the parameter I only get a basic message!

Is there a way of specifying which nodes are returned in the response message?

Thanks In Advance

Hi Tim,

I suppose one way of doing it could be to have two XML ports, once which is import only and a second which is by reference.

Within the codeunit which exposes the web method it might look something like:

SomeMethod(InboundXML : XMLport "Inbound Orders";VAR ProcessedOrders : XMLport "Orders Returned")

Within that do whatever you need to do with the data from the inbound call and finally pass back the 'streamlined' XML port.

ProcessedOrdersRec.SETRANGE("Date Processed", TODAY); // or whatever
ProcessedOrders.SETTABLEVIEW(ProcessedOrdersRec);

Not the cleanest way, admittedly, but it might solve the issue?

Hi SeeSharp,

how would that be rendered to the consuming web service? i.e. would the VAR be treated as the synchronous response?

Well the good news is that that solution does work! The bad news is the the request page leaves alot to be desired

Glad to hear, but yes, it's far from clean to work with. Not sure I know of a better / more efficient way though.

I suppose you could always develop your own solution which acts as a MITM between your service tier and whoever's doing the consumption? Additional overhead, but a little cleaner to the outside world.

You can try to use BigText as a parameter. In this way, if I am correct, you can process and return what you want...
